ChartMouseEvent#getEntity() and multiple series

blueser · Post by **blueser** » Mon Jul 16, 2007 9:01 pm

Hi,

if I receive a ChartMouseEvent for a coordinate where there are n data points (from n different series), which entity is returned by getEntity()? The "top" one (i.e. the last one rendered)? Is there any way to get a list of entities hit by the click?

TIA

Andre

I think it returns that last item drawn at that location. If you modify the mouseClicked() method in the ChartPanel class, you could probably have it return all entities under the mouse pointer. Someone else has asked about this before, but I haven't yet spent any time reviewing it...it sounds like a sensible enhancement though.

Hi David, thks for the reply.

Yes, please consider this for future versions

Maybe you could add a List<ChartEntity> getEntities() method that would deprecate the current ChartEntity getEntity() method... (just a thought)

Regards,

Andre
